  • Methodological bases of an estimation of residual bearing ability of support of a contact network.

    In this article authors examine integrated method of ring cross-section concrete constructions diagnostics after the example of overhead contact system pylons. Complex physical-mechanical process of carcass and concrete working needs to take into consideration the state of these components. Authors suggest modern device of magnetic-particle method making for carcass state rating and its location in a pylon body. Concrete jacket defectoscopy may be done with modified device population of ultrasonic diagnostics. Examination zones of constructions are found depending on pylons workload scheme. The authors give correlations which let determine parameters of destructions (cracks) that lead to degradation of load-carrying capability. In the article there are graphic materials got as a result of ultrasonic inspection and mathematical expressions for estimating of residual load-carrying capability with a glance of carcass and concrete destructions.
